Abstract

Inventia se refera la un procedeu si o masina de confectionat coarne conice, care, prin sudare, duc la obtinerea furcilor din agricultura. Procedeul, conform inventiei, consta în încalzirea barei de sectiune rotund sau ovala prin efectul caloric al curentului electric si racirea diferentiata pe lungimea barei, datorita aerului furnizat de niste duze montate la capete si a unor suprafete conice dupa care, aplicându-se o forta axiala, se alungeste bara pâna la rupere, obtinându-se doua coarne cu conicitate constanta. Pentru aplicarea acestui procedeu se foloseste o masina prevazuta cu un subansablu de taiere la dimensiuni a barei, un subansablu prevazut cu bacuri de strângere a barei si în acelasi timp de transmitere a curentului electric prin bara cu niste duze de suflare a aerului de racire si un carucior tras cu ajutorul unui cilindru hidraulic pentru aplicarea fortei axiale necesare ruperii.The invention relates to a process and a machine for making conical horns, which, by welding, lead to the forks of agriculture. The process according to the invention consists in heating the round or oval section bar by the effect of the electric current and the differential cooling on the length of the bar, due to the air supplied by some nozzles mounted at the ends and conical surfaces, after which, applying an axial force , elongates the bar until it breaks, obtaining two horns with constant conicity. In order to apply this method, a machine is provided with a bar-cutting subassembly, a subassembly provided with bar clamping bars and at the same time transmitting the electric current through the bar with some cooling air nozzles and a trolley pulled by a hydraulic cylinder to apply the axial force required to break.
